UNITED PATENT FFICEQ JOHN BROUGHTON, OF BROOKLYN, NE\V YORK.

SERVICE-COCK AND CASING.

SPECIFICATION forming part of Letters Patent No. 250,780, dated December13, 1881.

Application filed August 23, 1881. (No model.)

To .all whom it may concern:

Be it known that I, JOHN BROUGHTON, of the city of Brooklyn, in thecounty ot' Kings and State of New York, have invented certain new anduseful Improvements in Service-Cocks and Casings, of which the followingis a specification.

My invention relates to house service-cocks which are buried deep in theground and have spindles or rods exteudingto the surface whereby theirplugs may be turned, the cocks and spindles being inclosed in casingstokeep the dirt away from them.

My invention consists in the combination, with a serviee'cock and itsturning spindle or rod, of an external casing containing the cock andspindle or rod, and a socket upon the spindle or rod fitting the head ofthe cock-plug, and having a bearing upon the shell, whereby thecock-plug is relieved of the weight of the spindle or rod, and anydownward pressure thereon exerted in turning the same. The said socketis also preferably formed with a lug which enters a recess in thebearing on the shell, and, striking against the shoulders at the ends ofsaid recess, forms a stop for limiting the turning of the plug. Thespindle or rod is provided at its upper end with a cap or head, to whicha wrench is applied for turning the spindle and plug; and the inventionconsists in a novel manner of supporting the cap or head in the top ofthe casing, so that the top of the casing is closed to prevent theentrance of dirt.

In the accompanying drawings, Figure 1 represents a vertical section ofa casing, and

a side view of a cock and spindle arranged therein according to myinvention. Fig. 2 represents a similar view of the cock and apartially-seetional view of the socket upon the spindle or rod whichfits the plug, and a portion of the casing, all upon a larger scale thanFig. 1. Fig. 3 represents a sectional view of the top of the casing, anda side view of the cap or head of the spindle or rod, upon the samescale as Fig. 2; and Fig. 4 represents a top view of the casing and thespindle cap or head on the same scale as Figs. 2 and 3.

Similar letters of reference designate corresponding parts in all thefigures.

A designates the shell of an ordinary service-cock, and A designates theplug thereof.

In the meeting edges of the two parts of the casing B are formedrecesses 11, which fit circular'portions 0 upon the shell A of the cock,and when the two parts of the casing are secured together the cock isclamped between them.

0 designates the spindle or rod which extends centrally through thecasin g, and through which the plug A is turned. At the lower end thespindle or rod is provided with a socket, G, which is provided with anoblong hole, d, into which the oblong head 6 of the plug A fits, as seenin Fig. 2, thus locking the spindle or rod to the plug and insuringtheir turning together.

In order to take the weight of the spindle G and socket G 05 thecock-plug A, I provide the socket with a downwardly-extending lip orrim,f, which rests upon the top of the shell A at 9, whereby a bearingis formed which sustains the weight of the spindle and thecircumference, and the socket O has a lug,

h, which enters the said recess. The ends of the recess then formshoulders i, against one of which the lug It strikes when the plug isturned to full open, and against the other of which said lug strikeswhen the plug is turned to fully close the cock.

Upon the top of the spindle O is a cap or head, D, the top of which isof triangular or other form adapted to receive a wrench, and which hasan annular groove,j. The top of the casing B has a recess or depression,B, which receives the cap or head D, and at the bottom of said recess isan inwardly-projecting lip or flange, k, which enters the groove j andholds the spindle against longitudinal movement in either direction, aswell as sustains the weight thereof, and relieves the plug of allpressure. When thus constructed the cap or head D closes the hole in thetop of the casing and prevents the entrance of dirt.

Though the socket O and cap or head D are separate pieces, they arerigidly secured to the rod or spindle C, so as to turn therewith and maybe considered as parts thereof.

By my invention I prevent the plugs of service-cocks which are providedwith long turning spindles or rods from becoming tightly jammed intotheir seats, and therefore enable them to be more easily and quicklyturned from the surface of the ground.

What I claim as my invention, and desire-to secure by Letters Patent,is-

1. The combination, with a service-cock and its turning spindle or rod,of an external casing containing the cock and spindle or rod,

and a socket upon the spindle or rodfitting the head of the cock-plug,and having a bearing upon the shell, substantially as specified.

2. The combination of the cock-shellA, having a bearing, 9, recessed andprovided with shoulders i, the plug A, the spindle or rod 0, and thesocket O, fitting upon the bearing 9, and comprisingthelug h,substantially as specified.

3. The combination, with a service-cock and a turning spindle or rodhaving a cap or head provided with an annular groove, of an externalcasing having an inwardly-projecting flange fitting said annular groove,substantially as specified. 7
